Title: Zero-phase current transformer
Inventor: TOMAKI YOSHIAKI
IPC: H02H3/34
Filed: 1987-04-30
Abstract: PURPOSE:To correct the difference of the temperature characteristics of each optical current transformer by levelling zero-phase current components at every specified period and outputting a waveform subtracted from the zero-phase current component after a mean processing period ends. CONSTITUTION:A correction arithmetic circuit 11 is composed of an apparatus such as a microprocessor. One period of an output signal from an adding circuit 10 consisting of a sine waveform is divided, and sampling is conducted. Consequently, sampling signals reproducing sine waves at every one period are acquired. Signals obtained through sampling during a specified period are levelled at every dividing component, thus preparing a mean waveform composed of the sine waveform. The mean waveform acquired in this manner is memorized for the next processing period, and the previously memorized mean waveform is subtracted from the waveform of the output signal from the adding circuit 10 after the next mean processing period ends. Accordingly, zero-phase current components gradually changing by an ambient temperature are corrected to a sufficiently small value.

IPC: H04M1/27
Filed: 1986-05-09
Abstract: PURPOSE:To shorten waiting time from an outside line originating request to dialing by providing a decision means deciding a dialing permit sound after an outside line originating request signal is transmitted. CONSTITUTION:When an input means 11 indicates the circuit closing, an originating means 13 transmits the outside line originating request signal.
